Subject: [PATCH v2 06/11] eeprom: at24: add 24mac402/602 support
Date: Mon, 9 Jan 2023 14:08:17 +0100 [thread overview]
Message-ID: <20230109130822.1657470-7-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230109130822.1657470-1-a.fatoum@pengutronix.de>
The 24MAC chips feature an independent address mode for a MAC address.
Linux handles these by registering a device that's just 6/8 bytes of
size and that seeks to a fixed offset. In barebox, we'll just report
the real size and expect code to use the appropriate offset.
